(Or a ‘save-a-flush’ if your loo is new. Or small.)
Though it’s barely stopped raining long enough to dry your socks this summer, we’ve got a long-term trend towards having a bit less water because of climate change and population growth.
Luckily, it's very easy to save a bit of water. If you put a thing called a 'hippo' in your toilet cistern, it saves ten litres every day.
Hippos are easy to install and very well behaved. You'll barely notice he's in there at all. And, best of all, hippos are free.
Want one?
Yes, OK, I'll give a hippo a home.
(Already got one? To complete this nag grab another one for a friend or your workplace.)
